Fixed in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/5a2b012b10c7). You will need to build from Mercurial sources, or wait until the 3.8.0 release, in order to see the fix.

This problem likely has the same root cause as the one for ginput reported here:

When I do

the sine plots correctly, but the mouse cursor is off: it shows for instance that 'y'=0.994 when it is clearly above 1.

The screenshot shows the 'miscalculation'. Due to the screenshot, the 'cross' cursor has turned into a 'arrow' cursor, but I found this (tiny) bug using the cross-cursor.

The relative error seems to persist for bigger numbers too.

Octave+Gnuplot does it correctly.
